Publisher Summary This chapter reviews that aging has two rather distinct components: The “nuisance” factor and the mortality factor, resulting from the development of degenerative diseases. Diseases, such as arthritis, obviously have components of each. Both result at least in part from mutations in somatic cells.

Genetic factors in immunity and aging
Vaccine, 2000Maximum life span is controlled by genes that regulate molecular mechanisms accounting for the synchrony of structural and functional changes in different cells and tissues of each member of a given species. The role of immune response genes was investigated in aging mice genetically selected for high (H) or low (L) antibody response (Biozzi mice ...

Etiological Factors and Premature Aging
JAMA, 1962AGING IS an interesting subject which is receiving increasing attention in many fields. There is an ever-enlarging body of information which indicates that many of the phenomena which were previously regarded as "natural" processes resulting from old age are actually due to specific disease processes.

Age as a Factor in Australid Mentality
Perceptual and Motor Skills, 1967The article reviews briefly work done previously in the Central and Kimberley regions of the Australian interior. Investigations since 1962 had the initial purpose of comparing recent data with those obtained in 1929 and the secondary aim of attempting to demonstrate the effect of age on Maze performance.

THE brain is usually considered to be a structure. One does not intuitively recognize that structure depends on biochemical processes and that the development of structure and its maintenance are biochemical. Significant alterations occur when, and only when, biochemical processes are altered.

Growth factors and muscle ageing
Experimental Gerontology, 2004Loss of muscle mass (sarcopenia) is one of the main problems associated with ageing as it has major health care as well as socioeconomic implications. The growth hormone (GH)/IGF-I axis is regarded as an important regulator of muscle mass. However, it is now appreciated that other tissues in addition to the liver express IGF-I and that there are local ...

Nature, 1967
THE existence of a genetically determined β-lipoprotein polymorphism in human serum was detected by Allison and Blumberg1 and Blumberg et al.2, employing a precipitating antibody which was present in the serum of a repeatedly transfused patient (C. de B.) The same antiserum was investigated by Hirschfeld et al.3 and was shown to contain at least three ...

Factors affecting the age at menopause
Journal of Biosocial Science, 1979SummaryA postal questionnaire was sent out in September 1977 to all women aged between 40 and 60 years in Ede, the Netherlands. The design of the study was similar to that used by Jaszmann et al. in 1967 in the same locality. The response rate was 66·6%.

Homicide is a topic of interest not only because of its severity but because it is a fairly reliable barometer of all violent crime, especially as it affects women. This exploratory study compared a group of murdered women over age 60 with a group of murdered women 30-59 and included age-based factors for both groups. Discussion focuses on forensics as

The Age Factor in the Treatment of Glioblastoma
JAMA Neurology, 2016of diagnosed cancers in the United States will occur in patients older than 65 years. 2 It is logical to assume that this trend will also occur in the primary brain tumor, glioblastoma (GBM). This presents a problem for neuro-oncologists because older patients have been historically underrepresented in neuro-oncology trials.
